SMD Fuses . A fuse muaj ib txoj hlua hlau los yog hlau fuse lub caij, ntawm me me cross-section piv rau cov hluav taws xob hluav taws xob, mounted ntawm ib khub ntawm cov hluav taws xob terminals, thiab (feem ntau) nyob rau hauv ib lub tsev tsis-combustible.

Yog li, AC thiab DC fuses tib yam?

1 Teb. Qhov sib txawv tseem ceeb ntawm a fuse lub AC voltage ntsuas thiab nws DC voltage ntsuam xyuas yog ib lo lus nug ntawm muaj peev xwm nres lub arc uas tsim thaum lub fuse tshuab. DC arcs nyuaj heev los nres dua AC arcs, yog li koj yuav pom tsis tu ncua fuses uas yog ntsuas rau, hais, 250VAC tab sis tsuas yog 32VDC.

Tom qab ntawd, lo lus nug yog, SMD diode yog dab tsi? Thaum koj mus yuav khoom rau LED qhov muag teev, koj yuav ntsib ob hom LED (Light-Emitting Diode ). Ib qho yog LED tsis tu ncua, thiab lwm qhov yog hom siab dua uas hu ua ib qho SMD los yog Nto Mounted Diode ”.

Yog li ntawd, koj yuav kuaj fuses li cas?

Muaj ntau txhiab tus fuses uas muaj qhov sib xws, yog li koj yuav tsum tau ua kom meej thaum ntsuas lub fuse

  1. Cartridge Fuses: Ntsuas tag nrho qhov ntev ntawm lub fuse thiab txoj kab uas hla ntawm lub kaus mom.
  2. Lub raj mis Fuses: Ntsuas tag nrho qhov ntev ntawm lub fuse thiab txoj kab uas hla ntawm ob lub kaus mom raws li qhov feem ntau sib txawv me me.
  3. Hniav Fuses:

SMT txheej txheem yog dab tsi?

Kev tsim hluav taws xob siv hluav taws xob nto-mount technology ( SMT ) tsuas yog txhais tau hais tias cov khoom siv hluav taws xob tau sib sau ua ke nrog cov tshuab siv hluav taws xob uas tso cov khoom siv rau saum npoo ntawm lub rooj tsavxwm (luam tawm Circuit Board, PCB). Thaum nws los txog rau electronic assembly, SMT yog feem ntau siv txheej txheem hauv kev lag luam.
